ENGLAND.

To all whom it may concern:

Be it known that we, HENRY LEONARD HALL and CECIL ALEXANDER SHARP, both subjects of the King of Great Britain-and Ireland, residing at Langton Road, Cricklewood,in the county of Middlesex, England, have invented certain new and'useful Iniprovernents in Buildings and in 'Fitments of Same for 'theApplication' of Finishes to Surfaces, of which the following is a specification.

, This invention relates to improvenients in buildings and in 'fitrnents of same for applying finishes to surfaces which is par ticu'larly adapted for finishingofi' the surfaces of aeroplanes and other aircraft, which are covered with a fabric, and it has for its object the improvement of the conditions under which the persons applying the "finishes work, rendering the application of ,the finishes less fatiguing and deleterious to the health of the operators, reducing the floor space required for the operation, and generally increasing the output'and consequently reducing the cost.

;, We attain this end by arranging theparts to be treated so that the surfaces lie mainly in the vertical plane, by mounting said parts in horses or frames adapted to run in suitable guides, by arranging the drying chamber as a continuation ofathe applying or finished room'so that the horses or frames can be progressively passed from one to the other as the work proceeds, byarranging a heating battery at the end of the ap plying or finishing room farthest from the drying chamber for heating said applying,

or finishing room, by; arranging a second heating battery atthe junction of the applying or 'finishing room and the drying chamber for super-heating said d rying chamber,by providing means such as a fan or a blower for causing a current of air to passbysuction or pressure first over the heating-battery at the end: of the applying or; finishing room thenthrough saidroom into and throughithe drying chamber, by the, provision of suitable main andby-pass flues'forthe-air, and by the provision of suitable louvered screens," shutters or the like for regulating both the volume-and the velocity of the air passing intoitheapply- V Specification of Lettersiatent.

In-"both views similar 1 parts are-marked with like letters of references I V At one end of the applying or finishing room'a is a-compa'rtrnen't b'i'in which is located a heating battery 0 which may conveniently consist of a' series of hot water the drying chamber may be ,divided intocompartments as'shownQ it g Q 1 At the back end of the drying chamber is an exhaust flue or ductm which ,conn'nunicat on with the' drylng chamber a s'er1es"of openings n arranged a suitable level. Abov the dr ing chamber is a Joy-pass flue jor duct 1' the ront "of which opens intothe applying or finishing room andis provided with one or InOrejadJIuS'table shutters 8; Both the mainexhaust flue or duct m and' the b-y-pass flue or ductir lead into a chamber 6 in which 71s a circulating fan 4) of the suction type. f

The horses or frames h are supported and guided by suitable runners so: thatfthey T are rigid to.the pressui e exerted in applyfing the finishes, and when the'hea'ting battery c is arranged on thehfioo r as shown in Fig, 1 thebottom runners 7& of theho rses or frames are linounted "on alflrns' jh so that. theyf canlzriseand pass'eover ,js aid Patented A g. 19,.191o. Application fil'd October 21,1918. seria1-Eo.a5s,95s.*-' T Y i applying the finishes there is no necessity for the persons performing the operation to bend over their work thereby eliminating fatigue and consequently making for a greater output of work. The positions of the operators 'alsomake them practically immune from inhaling the fumes given off by the finishes thereby materially improving the conditions under which they work, and the position of the work is, such that both sides may be treated simultaneously.

What we claim'as our invention anddesire to secure by Letters Patent is 1. An improved building and fitments of Same for the application of finishes to surfaces such asthe parts of aeroplanesand the like, consisting of an applying or finishing room, a drying chamber contiguous to said room, a heating battery at the'end of vthe applying or finishing room farthest removed from the drying chamber, a second heating battery in the drying chamber, a series of horses or frames adapted to carry the work and to travel between-the applying or finishing room and the drying chamber,rand means for heating and circulating the air throu h saidroom'and chamber.
